Traefik Ingress Controller
我们在前面部署了 Traefik 作为Ingress Controller,如果集群外部直接访问Kubenretes内部服务的话,可以直接创建Ingress如下所示:
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: traefik-ingress
namespace: default
spec:
rules:
- host: traefik.nginx.io
http:
paths:
- path: /
backend:
serviceName: my-nginx
servicePort: 80
Traefik Ingress Controller
当我们处于迁移应用到kuberentes上的阶段时,可能有部分服务实例不在kubernetes上,服务的路由使用nginx配置,这时处于nginx和ingress共存的状态。参考下面的配置:
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: td-ingress
namespace: default
annotations:
traefik.frontend.rule.type: PathPrefixStrip
kubernetes.io/ingress.class: traefik
spec:
rules:
- host: "*.jimmysong.io"
http:
paths:
- path: /docGenerate
backend:
serviceName: td-sdmk-docgenerate
servicePort: 80
注意annotation的配置:
traefik.frontend.rule.type: PathPrefixStrip
:表示将截掉URL中的path
kubernetes.io/ingress.class
:表示使用的ingress类型
在nginx中增加配置:
upstream docGenerate {
server 172.20.0.119:80;
keepalive 200;
}
172.20.0.119是我们的边缘节点的VIP,见边缘节点配置。
